Application
Universal use in all material groups up to a strength of 1300 N/mm²
Execution
- Twist drill with unified shaft
- Diameter 1.00 mm–1.90 mm = tip angle 140°
- Diameter 2.00 mm–4.00 mm = tip angle 130°
- Diameter 4.10 mm–20.0 mm = tip angle 120°
- 2 drill heels
- 38° to 40° spiral angle
- Straight main cutting edge
Advantage
- Drilling without centring
- Problem solver in low-performance machines without internal cooling in high-strength steels and stainless steels
- Extremely hard, low-friction and temperature-resistant TiAlN coating for longer life
- Very high feed rates can be achieved
